Incompatibilities with older non-standard Android versions

[lars-olsson]

The section of the MainActivity.java runs into problems on older versions of Android (allowed under API requirement 8 given in the manifest) for this section of code:

public void setClockLw(View v) {
Intent intent = new Intent(
WallpaperManager.ACTION_CHANGE_LIVE_WALLPAPER);
intent.putExtra(WallpaperManager.EXTRA_LIVE_WALLPAPER_COMPONENT,
new ComponentName(this, ClockWallpaperService.class));
startActivity(intent);
}

This could be remedied by checking the version of Android, and disabling this if below API 16, or getting rid of this function altogether, and rely on the user enabling the live wallpaper from the standard way.

It might be somewhat discouraging if someone tries to follow this tutorial, runs on an older device, and finds it force closing on them.

Forgot to mention that the problem is due to the Intent WallpaperManager.ACTION_CHANGE_LIVE_WALLPAPER not being a requirement in Android prior to API 16.
